Did you use the Joomla un-installer to uninstall it, or did you just start deleting files? When you uninstall JFBConnect that way, it will disable all of the plugins and ensure that your site continues functioning as expected, without JFBConnect.
If that's not what you did, it would be helpful to know what files/directories you deleted before the problem arose. Here are some steps that should help in any case, but if not, knowing what you've done so far will help guide us the rest of the way:
* Edit the /plugins/system/jfbcsystem/jfbcsystem.php file. At line 44, you'll see:
function __construct(& $subject, $config)
{Add the following 2 lines directly after that:
parent::__construct($subject, $config);
return;That will disable the JFBCSystem plugin from operating and should fix you up. Alternatively, if you have PHPMySQL, you can use that to disable the JFBCSystem plugin in your database.
The System plugin is what's throwing that error and will hopefully let you into the admin area successfully after that change. From there, uninstall the extensions using the Joomla installer, though, if you already deleted files, you'll likely get some warnings/errors when trying that.
Let us know how it goes. If you decide to try JFBConnect again, we work very well with sh404SEF (and use both on this site, actually), so we should be able to help you work around any issues you encounter.
Thanks,
